Although the hospital's current buildings date from the 20th century, the Hospital de la Santa Creu (the last part of its name, "Sant Pau", was added in honour of the banker, Pau Gil, who paid the new buildings in the twentieth century) was founded in 1401 when six small medieval hospitals merged. The hospital's former buildings near the center of Barcelona date from the 15th century, and now house an art school (Escola Massana) and Biblioteca de Catalunya (National Library of Catalonia). Even though there is an ambulance in the picture it is no longer a hospital as it was closed in 2009.
